Where you put lusers so they can't hurt
anything. A program that limits a luser to a carefully restricted subset
of the capabilities of the host system (for example, the
rsh(1)
utility on USG Unix). Note that this is different from an
iron box because it is overt and not aimed at enforcing security so
much as protecting others (and the luser) from the consequences of the
luser's boundless naivete (see naive). Also
padded cell environment.
